Acanthochondria is a genus of copepods, containing the following species:

Acanthochondria limandae is a species of copepods in the genus Acanthochondria. They are host-specific ectoparasites of two species of flatfish: the common dab and the European flounder. They attach themselves to the bases of the gill arches of their hosts. They can infest as much as 2 to 30% of fish in a given population.

Acartia clausi is a species of marine copepod belonging to the family Acartiidae. This species was previously thought to have a worldwide distribution but recent research has restricted its range to coastal regions of the north-east Atlantic Ocean as far north as Iceland, the Mediterranean Sea and the Black Sea, with specimens from other regions assigned to different species.

Acartiidae is a family of calanoid copepods distinguishable by the rostral margin not being extended. They are epipelagic, planktonic animals, not being found below a depth of 500 metres (1,600 ft). There are over 100 described species distributed throughout the world's oceans, mainly in temperate areas.

Afrocyclops pauliani is an extinct species of copepod in the family Cyclopidae. A single specimen was discovered in 1951 in a small freshwater pool near Antananarivo, Madagascar, but the species has not been seen in collections since.

Artotrogidae is a family of copepods in the order Siphonostomatoida.

Calanidae is the largest taxonomic family of calanoid copepods. It includes the genus Calanus, which may be the most abundant metazoan genus on Earth.

Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them. Calanoid copepods are the dominant animals in the plankton in many parts of the world's oceans, making up 55%–95% of plankton samples. They are therefore important in many food webs, taking in energy from phytoplankton and algae and 'repackaging' it for consumption by higher trophic level predators. Many commercial fish are dependent on calanoid copepods for diet in either their larval or adult forms. Baleen whales such as bowhead whales, sei whales, right whales and fin whales rely substantially on calanoid copepods as a food source.

Calanus is a genus of marine copepod in the family Calanidae. The genus was split in 1974, with some species being placed in a new genus, Neocalanus. The following species are recognised:

However it has characteristically very long first antennae that exceed the body length. In addition, the females carry the eggs in a single sac rather than the twin sacs seen in Cyclops. It is a copepod of larger freshwater lakes and still waters.

Ectinosomatidae is a family of the Harpacticoida, a huge group of crustaceans belonging to the subclass Copepoda. Like most of their relatives, they are usually benthic inhabitants of marine environments.

In the epifaunal species, the first leg pair is often modified to allow the animals a better grip on the substrate.

Ergasilus is a genus of copepod crustaceans occurring in both the ocean and fresh water, often called gill lice. The females are parasitic upon the gills of fishes. Being copepods, gill lice have a single median eye on their head. The second antennae are modified into prehensile pincers. Male gill lice are free-living.
